ø9mm Dynamic Driver


The N11 seem to sound very good, hi-fi level: bright with an accurate sound, but very weak bass. However, these earphones were not designed for human ears, and actually need an amplifier to reach their full potential.


  • The mids and highs seem to sound very good, but since I can't get a proper seal, I can't be sure about the bass.


  • Needs a headphone amplifier to reach its full volume and sound quality potential.
  • Seems like bass was left out from these earphones, and the specifications actually confirm it.
  • Placing these inside your ears properly is impossible.
  • The build quality is bad. Very bad.
  • The ear tips you get here are disgustingly cheap.

Comfort & Fit

These earphones have a very uncomfortable form with short nozzles. Not designed for human ears.

The ear tips you get with these earphones are horrific. They are worse than the generic black tips you get with KZ products. I couldn't get a proper seal at all.

Lows / Bass

Since I can't get a proper seal, I can't evaluate the bass quality.

Mids / Vocals

From what I can hear, the vocals sound clear and detailed.

Highs / Treble

The earphones sound pretty bright and crisp, but can't be sure...
